Unfortunately, the quality of the photographs is too low to be able to glean anything from them.

If you have a low quality camera/phone like I do at the moment, there are two things you must do in order to ensure the highest quality photographs possible:

1. Make sure the subject is strongly lit--as brightly as possible. Cheap cameras can not produce details in low light situations. In your pictures, the strongest light is coming from the other side of the case, which can be discerned by the case's shadow on the wall.

2. Brace the camera (or phone) against something in order to avoid movement, which results in blur. I either set my phone on a surface so that it can't move at all, or if that is not possible, I use a broomstick or something else so that I can brace one end against the floor or other surface, and hold the stick and the phone at the same time. Whatever method you use, the device must be prevented from being a mover and shaker.

You've come this far--you might as well see if you can get a few usable photos.

I took a few photos with the LED's inside the case lit, but didn't bother posting them because I thought it wouldn't make much of a difference, here they are:

If you still can't see very much (which I don't think you can), I'll take some more photos, but that'll be the best I can do, because I simply do not have a better camera.

I would offer a suggestion: A reason why people (like my brother) want to buy pre-built computers is that they don't want to have to worry about fixing things themselves, or otherwise messing something up.

If you don't want to build your own computer, it seems to me that you should at least have the benefit of being able to take it to the store that sold it, or the person who built it, if something is not working correctly. It seems a really undesirable situation to have a new PC with an issue and an inability to do anything to fix it.

Do you not have any unnecessary items that you can sell in order to generate a cash reserve? At any rate, I hope that you can find someone who knows what they are doing and is willing to look at your PC, because that is what is needed if you can not take it to the seller and are unwilling to touch it yourself.

Ahhh it's a long story.
Long story short, if I screw something up, I don't have the money to replace it.

That is definitely the cause of your overheating problems, though, I'm sure. So you'll have to take the (non-existent) risk, if you want the issue resolved.

It would be less fiddly, if you removed the radiator from the case first, but judging by your pictures, it should be possible the unscrew the fans without removing it. Simply remove the four screws per fan, flip them around, and replace the screws. It will do wonders.

If you want to be extra cautious, power off (obviously) and unplug the PC, before getting to work. At least then, there's absolutely nothing that can go wrong.
